Problems solved by technology

For the second type of problem, the problem can only be found by online user complaints; after the user complains and finds such a problem, the maintenance personnel will manually dial and locate the problem, which is inefficient; and for the first type of problem, if the NSS side does not actively detect it in time The state of the A interface circuit, unless it is abnormally serious and causes network congestion, can only be known through the user's complaint to the BSS operator; otherwise, only part of the A interface circuit is unavailable, which will lead to a waste of A interface circuit resources and reduce the call connection rate during busy hours. BSS system maintenance personnel cannot find such problems

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] The basic composition of the complete GSM local network system is as follows: figure 1 As shown, it includes two parts: BSS and NSS. BSS is composed of BTS1, BSC2 and TRAU unit 3, while NSS is composed of MSC5, visitor location register (VLR) and home location register (HLR). The interface between the BSS and the NSS is the A interface 4 .

[0025] The principle diagram of the A interface circuit monitoring method of the GSM communication system is as follows figure 2 shown. The solid line part is to realize the A interface circuit monitoring function and needs to change the design of the relevant parts of the GSM system; and the dotted line part is the part that needs to be involved in the realization of the monitoring function but does not need to be designed. These parts only realize the original Some basic functions are enough.

Abstract

This invention provides a monitor method for inference circuit A of inserted TARU unit in radio communication system which can identify timely the exception resulting in interface A not working, and identify timely the abort of up group circuit transmission between BSC exchange unit and TARU resulted from various software and hardware to switch interface A based on it to avoid it idle to increasethe busy connection rate and increase of the service quality and maintenance BBS network to ensure the service quality of radio communication network.

Description

technical field [0001] The invention relates to a monitoring method of an interface circuit of a wireless communication system, in particular to a monitoring method of an A interface circuit between a base station subsystem (BSS) and a network subsystem (NSS) in a GSM communication system. Background technique [0002] A complete GSM local network system includes two parts, BSS and NSS. BSS is composed of base station system (BTS), base station controller (BSC) and code conversion and rate adaptation unit (TRAU), while NSS is composed of mobile switching center ( MSC), visitor location register (VLR) and home location register (HLR). The interface between BSS and NSS is A interface, and A interface is an open standard interface. The BSS products and NSS products produced by various equipment manufacturers must support it, so that the BSS products and NSS products of different manufacturers can be interconnected and interoperable to form an inte...
